iSpring F19K75 2-Year Replacement Supply Set

The F19K75 3-year filter pack contains a total of 19 replacement filters so that the filters can be replaced regularly for a span of 3 years. It includes 4x 5 Micron 10" Sediment Filters (1st Stage, #FP15) which effectively remove dirt, rust, sand, and other particles. These should be replaced approximately every 6 months. Additionally, it comes with 4x 5 Micron 10" Granular Activated Carbon (GAC) Filters (2nd Stage, #FG15) which absorb chlorine, halide, organic contaminants, odors, and other impurities that can cause bad tastes and odors. These should also be replaced every 6 months. Furthermore, it includes 4x 5 Micron 10" CTO Carbon Block Filters (3rd Stage, #FC15) which remove any remaining chlorine, tastes, and odors and should be replaced every 6 months.

The pack also contains 1x High Rejection .0001 Micron TFC Reverse Osmosis Membrane (4th Stage, #MC7) which is the main component of the RO system. It produces drinking water at a rate of 75 gallons per day and should be replaced every 2-3 years. Additionally, 2x Post Carbon Inline Filters (5th Stage, #FT15) are included in the pack. These filters polish the water from the tank before it is delivered to the faucet and should be replaced every 12 months.

Furthermore, the pack includes 4x Alkaline pH Remineralization Filters (6th Stage, #FA15) which add 0.5 - 0.8 pH back to the water. These filters also add back healthy minerals such as ionized calcium, magnesium, sodium, and potassium which are removed during the RO process. They should be replaced every 6 months.

This filter pack is compatible with the iSpring RCC7AK, RCC7P-AK, and most other RO systems that use standard-sized filter housings including Flowmatic, PuROLine, Crystal Quest, and Apec.

The product description includes a breakdown of what is included in the pack, including the number of each type of filter. It also specifies the models of RO systems that the pack fits. The specifications and dimensions of the filters are provided, including their length, outer diameter, and fitting size. The weight of the pack is stated as 19 LBS.

These individually wrapped filters are designed for most standard 6-stage RO systems and provide clean, safe, and great-tasting water every time you use the faucet. They improve the quality of ice cubes, tea, coffee, food, and even baby formula. The 75 gpd RO membrane ensures superior performance with a high rejection rate for total dissolved solids (TDS) of up to 97%. However, it should be noted that the RO membrane removes some helpful minerals along with harmful pollutants, resulting in slightly acidic water with a pH of 7.0 or below. To counterbalance this, the alkaline mineral filter produces alkaline water with restored healthy minerals like natural calcium, magnesium, and potassium ions that balance the pH of the RO water.

In total, the pack includes 19 pieces of 10" x 2.5" replacement water filters, which consist of 4x sediment filters, 4x granular activated carbon filters, 4x carbon block filters, 1x 75 gpd RO membrane, 2x post-carbon filters, and 4x alkaline filters.

The updated FA15 alkaline mineral filters and FT15 post-carbon filters are designed with a secure push-fit quick connection, making filter replacement faster and more convenient. If you encounter any difficulties during installation, please refer to the user manual or contact us for assistance.
